Hung up ankle reflex seen in -

Hung up reflex is a deep tendon reflex in which, after a stimulus is given and the reflex action takes place, the limb slowly returns to its neutral position. This prolonged relaxation phase is characteristic of reflexes in persons with hypothyroidism. It is also known as Woltman sign.

Delays in relaxation time in patients with hypothyroidism appears to be propoional to the level of thyroid-hormone deficiency.
